brake GMC YUKON DENALI 2005 User Guide

The sunroof is also equipped with a sunshade which
can be pulled forward to block sun rays.
If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop
at the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracks.
If the battery has been recharged, disconnected or is
not working, the sunroof may need to be reprogrammed.
To do this, start the vehicle and press the forward
side of the sunroof button until the glass panel moves to
a fully closed position. Release, and press again to
move to the vent position which occurs when the sunroof
is fully tilted rearward. This will reset the memory and
enable the sunroof to function properly.Vehicle Personalization

Cruise Control
9(Off):This position
turns the system off.
R(On):This position activates the system.
+ (Resume/Accelerate):Push the lever to this symbol
to make the vehicle accelerate or resume to a
previously set speed.
T(Set):Press this button to set the speed.
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
If you apply your brakes, the cruise control will shut off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
3-11

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The cruise symbol on the
instrument panel will
illuminate when the cruise
control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch briey from on to
resume/accelerate.
You’ll go right back up to your chosen speed and
stay there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
3-12

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed.
Press the set button at the end of the lever, then
release the button and the accelerator pedal. You’ll
now cruise at the higher speed. If the accelerator
pedal is held longer than 60 seconds, cruise control
will turn off.
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch. To
increase your speed in very small amounts, move the
switch briey to resume/accelerate. Each time you
do this, your vehicle will go about 1 mph (1.6 km/h)
faster.
Reducing Speed While Using Cruise
Control

Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
To turn off the cruise control, do any of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Shift the transmission to NEUTRAL (N).
If your vehicle has the StabiliTrak®feature, cruise
control will turn off if road conditions cause
StabiliTrak
®to activate.
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
3-13

Voltmeter Gage
When your engine is not
running, but the ignition is
in RUN, this gage
shows your battery’s state
of charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage may
transition from a higher to lower or a lower to higher
reading, this is normal. Readings between the low and
high warning zones indicate the normal operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
With the ignition on, the brake system warning light will
ash when you set the parking brake. The light will ash if
the parking brake doesn’t release fully. If you try to drive
with the parking brake engaged, a chime will sound when
the vehicle speed is greater than 3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided into two
parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on and a chime sounds there
could be a brake problem. Have your brake system
inspected right away.
3-34

This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push or may go closer to the oor. It may take
longer to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 4-50.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service. United States

3-35

Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.
That’s normal. If the light doesn’t come on then, have it
xed so it will be ready to warn you if there is a problem.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. You will also hear a chime
sound when the light is on steady. If the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes. If the regular brake
system warning light is also on you don’t have anti-lock
brakes and there’s a problem with your regular brakes. In
addition to both lights, you will also hear a chime sound
on the rst occurrence of a problem and each time the
vehicle is shut off and then restarted. SeeBrake System
Warning Light on page 3-34.
Traction Off Light
If you have the
StabiliTrak®system, this
light should come on briey
when you turn the
ignition to RUN.
If the light doesn’t come on then, the system may
require service; have it xed so it will be there to warn
you if the system is turned off.
For more information on the traction off light, see
StabiliTrak
®System on page 4-8.
